Ah, this makes me sad. I really don't think you can or should live like this for much longer let alone the rest of your life. Yes, get skype and stay in touch that way daily. BUT, you need to speak to your husband regarding long range plans. Honestly, NO job is worth this type of lifestyle. One of you can change. If your job is the count on, stable, consistent job, then you stay working and he quits his current job and finds work doing something similar in your area. OR, you must realize that while your job is good, you will find another similar near your husband. You haven't because you haven't had to. Leaving your job will make you have to find that job near him. It is hard for me to relate on a cultural level as I'm from the states and we an freely make change in our lives to suit us--- but regardless, family should be valued in any culture and making some sacrifice and hard decisions putting family first is in order here. good luck
You have many blessings, that i'm glad that you are grateful, however you also have hardships that many do not have to deal with. the absence of a husband and a long distance relationship. I think you need to talk to a therapist about your depression, and learn how to effectively deal with it. You can also go on the Depression Community and read how others combat depression, and maybe post about how to best handle long distance relationships and it might be helpful to you. Do you skype daily?
